Vietnam’s top security official has been appointed the country’s new president. The post is the second highest in the country’s political hierarchy.

Vietnam’s National Assembly on Wednesday elected To Lam as President. His appointment comes after a series of dismissals from the Communist Party’s politburo.

Lam is 66 years old. He spent over four decades in the Public Security Ministry and became its minister in 2016.

Lam is the third person to be appointed president in the past year-and-a-half. His two predecessors had resigned amid an ongoing anti-corruption campaign.

The crackdown is being spearheaded by the party’s General Secretary Nguyen Phu Trong, the country’s top leader.

Earlier this week, the National Assembly also appointed its new chairman after his predecessor had stepped down this month.

An expert on Vietnam’s politics from ISEAS-Yusof Ishak Institute, Nguyen Khac Giang, said there could be fierce political infighting among the top leadership.

He also said growing uncertainties in politics could affect the country’s economic environment as concerns are rising among foreign investors.

Giang said, “When the political situation at the top has not been resolved, the bureaucracy will remain kind of like paralyzed at some point.”

But he added the confusion won’t last long, and the situation is expected to be stabilized once a new leadership is established within a couple of years.
